But former Manchester United legends Rio Ferdinand and Michael Owen played down any chances of ill-feeling between Salah and his team-mate.

"I hope (he is celebrating),' said the former Manchester United defender. 'The bond they have on the pitch at the moment, I think Salah is celebrating in his own way. His hands are up at the beginning of that," Rio said.

"I think he is happy,"Owen simply added.

Firmino sealed victory for the Reds in their Champions League opener to stay on top of Group C.

After going two-goals up from Daniel Sturridge and James Milner's penalty earlier, Thomas Meunier and Kylian Mbappe struck back for Thomas Tuchel's side.
